SPRING BED-BOTTOM.

Application filed March 4, 1912.

To all whom it may concern.

Be it known that I, J OSEPH P. LEGGETT,

a citizen of the United States, and a resident of Carthage, in the county of Jasper and State of Missouri, have invented a certain new and useful Improvement in Spring Bed-Bottoms, of which the following is a specification.

My invention relates to lmprovements in spring bed bottoms.

It relates particularly to spring bed bottoms in which single cone coil springs have their lower coils supported on slats. As usually constructed these slats are cross slats which are disposed crosswise of the bed and have their ends supported upon rigid unyielding side bars. With such constructions the outer springs of the bed bottom being disposed above or adjacent to the rigid unyielding sidb bars, are subjected to undue strain in their smaller coils, when one sits on the side of the bed, as when going to bed or arising therefrom. This undue strain upon the smaller coils of the springs causes them to weaken and shortens their terms of usefulness.

The object of my invention is to provide a structure in which these injurious strains are to a great extent eliminated, and which at the same time will be more comfortable to sit or lie upon.

I accomplish this by providing flexible, resilient, longitudinal slats for supporting the coil springs, the slats being supported only at the ends, that is at the foot and head of the bed. By providing flexible resilient slats, the slats, as well as the springs, will yield, when a person sits upon the side of the bed, there being no rigid side bars to prevent vertical movement of the slats. After the weight of the person has been removed, the bed bottom will, owing to the resiliency of the slats, instantly reassume its normal form.

By having the spring supporting slats disposed lengthwise of the bed, a maximum of vertical movement in the slats may be effected, owing to the greater length of the slats, as compared with the usual cross slats. The use of the longitudinal slats also permits the dispensing with rigid side bars in the bed bottom, thereby reducing the weight and the cost of making the bed bottoms. Furthermore by eliminating the rigid side bars of the bed bottom the outer rows of Specification of Letters Patent.

springs will lower to the same extent as the interior springs, upon a person sitting upon the side or edge of the bed. For the same reason a person can lie close to one side of the bed without tendency to roll toward the middle thereof, as would be the case were the outer slats rigid and unyielding. The bed bottom is, therefore, more comfortable to sit or lie upon than in structures in which the outer rows of springs are mounted upon rigid unyielding supports.

In the accompanying drawings which illustrate the preferred form of my invention, Figure 1 is a top view of the bed bottom shown mounted on a bed frame, and with the coil springs removed. Fig. 2 is a side elevation of the bed bottom, the bed frame being shown in dotted lines. Fig. 3 is a view similar to Fig. 2-, excepting that the springs and slats are shown depressed, as would be the case when one would sit upon the edge of the bed. Fig. l is a bottom view, some of the coil springs being removed. Fig. 5 is a cross section on the plane of the line a b of Fig. 1, the coil springs being shown, and the bed frame dotted. Fig. 6 is a cross section through two of the outer longitudinal slats. Fig. 7 is a plan view of a portion of the structure showing a portion of one of the longitudinal slats, one of the springs and portions of two of the cross bars or braces.

Similar reference characters designate similar parts in the different views.

Two cross slats l, disposed one at the head and one at the foot, are provided. These slats are preferably rigid bars disposed edge up, and they have secured to them the ends of a plurality of flexible, resilient, longitudinal slats 2 which support the smaller bottom coils of inverted single cone coil springs 3. The bars or cross slats 1 preferably have portions lextending laterally beyond the outer slats 2, which portions are adapted to rest upon and be supported by the bed frame, which is designated by 5.

The longitudinal spring supporting slats 2 are preferably flat bars disposed edge up and they are preferably connected with each other by cross braces 6, preferably U shaped and having their arms rigidly secured to the slats 2. The braces 6 serve to prevent lateral flexing and twisting of the slats 2, while permitting said slats to be flexed vertically. The braces 6 may also be provided with lips 7 on the arms thereof, which extend over and hold the lower coils of the springs 3 against the slats 2.

The portions 4 of the-cross slats 1' may extend upwardly and outwardly so as to drop the slats 2 below the upper sides of the side rails of the bed frame 5.

If a person sits upon the edge of the bed, the springs 3 and slats 2 will be depressed as shown in Fig. 3. The slats 2 being supported only at the head and foot of the bed will readily yield to the pressure applied to the springs, thereby relieving the smaller coils of vthe springs of much of the strain which, otherwise would be applied to them.

I do not limit my invention to the structure shown and described, as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

Having thus described my invention,what Iclaim and desire to secure by Letters Patent, is

1. A springbed bottom having cross slats at the head and foot for supporting the bed bottom on a bed frame, flexible resilient longitudinal slats supported at their ends by said cross slats and unsupported intermediate their ends, and coil springs supported by the longitudinal slats.

'2. A spring bed bottom having cross slats at the head and foot for supporting the bed bottom on a bed frame, flexible resilient longitudinal slats supported at their ends by said cross slats and unsupported intermediate their ends, the cross slats extending laterally beyond the outer longitudinal slats, and coil springs supported on the longitudinal slats.

3. A spring bed bottom having cross slats at the head and foot for supporting the bed bottom on a bed frame, flexible resilient longitudinal slats supported at their ends by said cross slats and unsupported intermediate their ends, the longitudinal slats comprising bars disposed edge up, braces connecting the longitudinal slats which permit vertical but not lateral flexing and which hold the longitudinal slats from twisting under pressure, and coil springs supported on the longitudinal slats.

4. A spring bed bottom having cross slats at the head and foot for supporting the bed bottom on a bed frame, flexible resilient longitudinal bars disposed edge up and supported at their ends by the cross slats and unsupported intermediate their ends, and coil springs supported on said bars.

5. A spring bed bottom having two rigid cross slats, one at the head and the other at the foot, flexible resilient longitudinal slats supported at their ends by the cross slats and unsupported intermediate their ends, thecross slats having portions pro]ect1ng unsupported intermediate their ends, the

cross slats having portions projecting laterally beyond the longitudinal slats for supporting the bed bottom on a bed frame, braces connecting the longitudinal slats which permit vertical flexing but hold the longitudinal, slats from lateral flexing or twisting, and coil springs supported on the longitudinal slats.

7. A spring bed bottom having two rigid cross slats, one at the head the other at the foot, flexible resilient longitudinal bars disposed edge up and supported at their ends by, said cross slats and unsupported intermediate their ends, the cross slats having portions extending laterally beyond the outer longitudinal slats for supporting the bed bottom on a bed frame, braces connecting the longitudinal slats which permit vertical flexing of the longitudinal slats but which hold the longitudinal slats from lateral flexing or twisting, and coil springs supported on the longitudinal slats.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
